- Application filed May 9, 1923. semi-"No. 637,634.

This invention relates to loose-leaf binders and has for its primary object to provide a device of this character which .may be very easily and quickly manipulated for I the insertion or removalof additional sheets or leaves, 1 a I It is another object of my invention to provide a binder of such a construction thatnear the hinge line of the ledger. covers, thus causing the sheets'or leaves to lie perfectly flat when the ledgerxis open and enabling the user to inscribe or write upon said sheets nearer'to the post-receiving holes than is possible in devices of this character as heretofore constructed.

It is an additional object of the invention to provide improved latch means .for holding the complemental back sections in adjusted relation to each other and which may also be very easily operated to quickly ,eifectthe necessary. adjustment.

1 With the, aboveand other objects in view, the invention consists in theimproved looseleaf binder and in the form; construction and relative arrangement of its several parts as will be hereinafter more fully described, illustrated in the accompanying drawings and subsequently incorporated in the subjoined claims.

In the drawings, I have illustrated a ledger ofv conventional form' having cover members 5, which, in the construction shown in Figure 1', are connected to the rigid binder strips 6 by the leather hinges 7 To the respectivebinder strips 6, the com ple'mentalbinder sections 8 and 9 respectively, are secured. Each of these sections is formed from a sheet-m'etalplate, the section I Shaving a back flange 10 and a relatively narrow flange 11 disposed at right angles to the flange l0 and suitably secured to one of the strips 6; Theother section 9 has a similar back'flange 12 and a flange 13 eX-- tending angularly from one edge thereof. .As shown in Fig. ,5 of the drawings, the flanges li and 13 of the binder sections are secured ,to the respective strips 6 by means of the screws 14 which have threaded 'en- 99 gagement in sleeves 15 engaged in coinciding openings in the flanges and. the strips 6. The inner ends of "these sleeves are flanged as at 16. However, it will be apparent that various other meanslmight "be v employed for, securing the sheet-metal binder. sections to the strips -6'of the ledger.

The binder section 8 at the ends of its back flange 10 is bent inwardly to provide the grooves or channels l7'extending the full height of the back flange, s'aid back flange being 'angularly extended' from said channels to "provide the end flanges 18,- eachof which [is formed with aninwardly proj cting1ug19 securely riveted as at 20 to the flange 11. r

Upon the outer side of each of the'end flanges 18 a pivoted latch member 21 is mounted, the free end of said latch member being angularlydisposed as. at 22 and 19 9 wise may be conveniently formedirom sheet 7 metal, and in a preferred embodiment, .are

of fiat rectangular cross-section as seen in Figure 3=ot 'the drawings, each post being pr'ovided'with a base extension 26'riveted or otherwise securely fixed to the flange. 11.

The other binder, section 9 likewise has its back flange 12 bent upon itself at the ends thereof to provide ribs 27 for telescoping sliding engagement in the grooves or channels 17 ,ot the binder section 8. Fro'mthese ribs keeper flan es 28 project at right angles to the back 1 ange '12, said keeper flanges at the ends thereof adjacent the flange 13, having notches or recesses 29. At their other endsth'e keeper flanges are formed nvith the; beveled or inclined edges 30.; At their notchedends the flanges 28 arealso formed with inwardly projecting lugs 31 which are riveted to the flange 13. I ,e

Upon the flange l3 spaced leaf-holding posts 332 f similar construction to theposts 25 are arranged, and when the two binder sections are assembled, the posts on one section are alternatelydisposed with rela tion to the post jon the other. section and in line therewith, it being understood that these Josts en a 'e'through the o oenin 's in b 2; i b

the. ends or thele'aves or sheets in the usual manner. v i Y .In the use of the improved binder as above described, thecover 5 and binder strip-6 carrying thejbinder section'8 is positioned uponthe desk or table and the superposed she'ets or leaves-are arranged thereon, with the posts extending through two of the openingsiin eachleat. The other cover-member 5'isthen positioned upon the leaves ndftherib -27 ofthe binder section 9 are engaged iii-the channelsor grooves 17 and said binder section forced dOivnwardly sothat 'itsfback flange12 is disposed in overlapping relation with the flange 10 of the section 8 against. the inner side thereof. Theposts. 32 oft-hesection 9 of course, enter the otheiiopenings in the leavesv or sheets. In vthis telescoping connection of the two binder sections, 'theinclined edges- '30 on the "keeper flanges 28 ride against theinwardly projectingends 22. of the latch members 2 1, ,d-is lacin s'ai'd latch members from a n-.nennn p siaep aga nst the actionof the sjiiriligs 9A itntil tlienotches 29 inthe flan es 2s win'cide with "the opening ".23.

The inturned ends 22 oiithe latch members then snap into the notches 29 under the action of the springs 24:, thus lockin the two sections-of the binder in assemble; relation. it will be seen that by reason of this construction, the back of the binder is completely closed. \Vhen the ledger is opened,

the leaves or sheets lie perfectly fiat and in view of the fact that the posts 25 and 32 are located atc the extremeedges ofthe flanges 11 and 13 respectively,and closely adjacent to the hinge line of the cover, the user may write upon the sheets very close to the post-receiving openings therein.

In order to add additional sheets or remove sheets from the ledger, it is only necessary for the user to move the ends of the latch members 21 to the right in the slots thereby disengaging said members "from the notches 29 sothat the two complemelv tal binder sections can be disconnected. After the removal of the leaves or insertio'n ot new or additional leaves, the two sections canbe again quickly connected in the manner above described. The parts are very rigidly held against relative Shifting movement or the danger of accidental disconnection so that the ledger maybe freely handledlwithout liability of separation of the cover members from each other or the release or disarrangement of the super'l'aosed leaves or sheets. 1

In Figs. 6 to 9 inclusive of the drawings, I have illustrated alternatives for several of the structural features of the device above described. Thusas seenin 6, instead 0+2 providing leather hinge connections 'between the cover members 5 and the binder strips 6, I may attach 1netal'straps33and Sethto the members and strips respectively, and connect said straps bymeans of commonpintle hinges Q In 7, ,1 ha eillus'trated anothermanher of attaching the leaf-'receii' ing posts to theiian'ges ot .the binder'sections, Thus, each of the sheet-metal posts may lbe'pro vided at one otits ends with the angula'rly disposed space-d flanges 36 between which the edgeotf'theflange on the binder section isfreceive d, said iianges being rigidly secured to eachotherby the rivet I in Fig. 8 o't'the drawings I show the latch keeper flange as provided witha plurality of spaced notches 29 to receive the inwardly projecting; hook on thelatch member. Thus the. two telescoping-1 sections or the binder can'he adjusted with relation to each other so as to increase the capacity the ledger/ In'Fig. 9, a slightly diiie'rentf'l'orm of the pivoted latch member is illustrated, said member beingprov-ided at its free end with an outwardly extending-bend or loop 38 which projects slightly beyond the plane of the end edges of the binder strip 6 'so'that said loops o bead maybe easily engaged by the fingers to move the latch members'to release position when it is desired to open the to increase the capacity of the binder even beyond that which would be permissible when the means shown in Fig. 8 is provided for the relative adjustmentof the two binder sections. In such instances, I employ 21. Supplem'entary duplex binder section. As shown in Fig. 11 ofthe'drawings, this supplementary section consists of two sections 8 and 9', identical as to structure with those here-' inbefore described. These single sect-ions designated by the numerals 8 and 9 respectively. in Figure 11, are arranged with their back flanges disposed-in the same plane and their attaching flanges in opposed contact ing relation. These attaching flanges are rigidly and permanently secured together by means of the rivets 39 which secure the leafengaging posts to the respective flanges and from which said posts projectin relatively opposite directionsand in staggered relation to each other. e 1

When it is desired to increase the capacity of the ledger, it is only necessary to release the latch members 24 and lift the upper cover of the ledger and binder strip 6 carrying the binder section 9.' The duplex supplementary section is then arranged in position, the end ribs on the part 9 thereof telescoping in the channels 17 of the other binder section to the strip 6. The additional leaves or sheets are then arranged upon the upwardly projectingposts of the part 8 of the supplementary section and the cov r 5 with the binder section .9 is then replaced. the latch members at the ends of the part 8 engaging the keeper flanges as above referred to, while the latch members on the section 8 engage the keeper flanges on the part 9 of the supplementary section. Thus as will appear from Fig. 10 of the drawings the several parts are securely locked together and provide a ledger of relatively large ca pacity. Of course, the capacity "of the ledger might be even further increased by the use of another supplementary duplex section of the form shown in Figure 11 of the drawings. g g

From the foregoing description considered in connection with the accompanying draw-' ings, the construction, and manner of use of my improved loose-leaf binder will be clearly understood. Owing tothe elimination of all threaded post connections such as have heretofore been employed in devices of this character, it will be apparent that the binder can be very easily and quickly opened and closed for the removal or insertion of sheets or leaves. The relatively simpleand light construction of the several parts provides a binder which may be employed in connection with very large books or lodgers without tions each having the leaf-holding-posts, the

Yunduly increasing the weight thereof and by v i the provision, of the suplemental duplex sec- I capacity of the 'ledger'ca'n be readily increased to any extent desired with the assurance that all-of the-leaves or sheets will be held between the two cover members with the same degree'of security. Also, it will be appreciated that the structure affording a sliding telescoping connection between the several sections of the binder provides at all times a completely closed back for the ledger and renders the structure as a whole, very substantial and *dura'ble and resistant to excessive strains.

I haveherein referred to a construction of my improved loose-leaf binderwhi'ch has been found in practice to give highly satisfactory service, nevertheless it is to be understood that the embodiments of the invention whichl have selected for purposes, of illustration may be sifisceptible of many other I structural I herein referred to and I therefore, reserve the privilege of adopting all such legitimate changes as may be fairly embodied within the spirit and scope of the invention as claimed.
